    Beta-delayed proton emission of magnesium-20 and the RCMP silicon detector array
    (Faculty of Graduate Studies and Research, University of Regina, 2024-09) Liu, Jizhong; Grinyer, Gwen; Berg, Marcella; Mobed, Nader
    In 2011, experiment e09024 was performed in National Superconducting Cyclotron Laboratory(NSCl) located at Michigan State University from Michigan state. The goal was to investigate delayed particle emission for isotopes near proton drip line. The main secondary beam was ²²Si while other exotic beam such as ²⁰Mg,²²Al,²³Si was also produced. The delayed particle emission from ²⁰Mg is of particular interest in this thesis and has been studied in details. In 2018, Dr.Gwen Grinyer's group at University of Regina started constructing a Silicon Detector Array named Regina Cube for Multiple Particle(RCMP) used for studying delayed particles at proton drop line with high resolution and high solid angle coverage. The detector is designed to be placed inside GRIFFIN chamber located at TRIUMF cyclotron facility. GRIFFIN chamber designed by GRIFFIN collaboration consists of 16 High Purity Germanium detectors with 8 fast timing LaBr3 used for studying gamma rays. It is a high effociency detector chamber with BGO shielding for Compton suppression. The combination of the two could provide more detailed study of nuclear structure for isotopes near proton drip line. The detector has been deployed in 2024 and a new experiment on ²⁰Mg S2232 is being scheduled during 2024 summer. In this thesis, I will be presenting analysis of ²⁰Mg from experiment e09024 with development and testing of RCMP detector array and experiment S2232.
